TLS cipher suites and ConfigMgr client notification channel

Recently discovered that when the ConfigMgr client connects to the MP on TCP 10123 the client is offering the following TLS cipher suites, TLS_RSA_WITH_AES_128_GCM_SHA256, TLS_RSA_WITH_AES_128_CBC_SHA256, TLS_RSA_WITH_AES_128_CBC_SHA which are considered weak. If these are disabled on the server the TLS handshake fails and the client will fall back to HTTP.

Are there any plans to use more secure ciphers in the future?
